Manual shift transmission and clutch assembly therefore

A clutch assembly for a manual shift transmission comprises:

• a first shaft carrying a first clutch disc;
• a second shaft that is coaxial to the first shaft and carries an axially shiftable second clutch disc, a first ramp, of which at least one section describes a helical line that is coaxial to the first and second shafts, and a first actuating body, which is clamped between the first ramp and the second clutch disc;
• wherein the first actuating body is movable about a common axis of the first and second shafts between an open position, in which the first and second clutch discs are spaced from one another, and a closing position, in which the first and second clutch discs contact one another in a frictionally joined manner,
• wherein the first actuating body is received in bores of a holder that is rotatable about the second shaft, and
• wherein a link formed with a helicoid slot section and rotatable with the holder and a cam is engaged within the slot section and coupled to a gear shift sleeve to translate the gear shift sleeve axially along the common axis between a neutral position and a locking position corresponding to the open position and the closing position, respectively.
